Five of the best iPhone games

Just like the real air hockey you play in arcades, the iPhone version allows you to play with two players. By using the iPhone's multi-touch capabilities you can play with a friend on a single handset, each person holding on to their mallet using a finger. If you don't have anyone to play with, you can play against the computer, which is genuinely challenging. It costs 59p to download and is a great one for road trips with friends.
